hadoop集群某个节点某块盘出现“只读文件系统”

[chengqian918]

如标题所述，出现某个数据盘为"只读文件系统"。
对该盘进行格式化后，重启hadoop应用，过一会又出现“只读文件系统"的问题；
看系统日志，出现以下错误：
kernel: sd 0:2:2:0: Unhandled error code
kernel: sd 0:2:2:0: SCSI error: return code = 0x00070002
kernel: Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_OK

kernel: EXT3-fs error (device sdc1): ext3_journal_start_sb: Detected aborted journal
kernel: Remounting filesystem read-only
kernel: __journal_remove_journal_head: freeing b_committed_data

请问出现此问题的原因是什么，hadoop自身应用的bug？还是？

ha都应该配journal来存储元数据的吧，不知道楼主是否配了journal
